AN-X-DHP Module Overview
The AN-X-DHP communications module connects a computer or other
device to an Allen-Bradley Data Highway Plus network, using Ethernet.
The module:
•
Can act as any valid Data Highway Plus station number, from 0 to 77
octal
•
Supports all Data Highway Plus baud rates, 57.6, 115.2 and 230.4
Kbaud
•
Maintains Data Highway Plus diagnostic counters
You can use the AN-X-DHP module with Rockwell programming
software to communicate with PLCs such as the PLC-5 or ControlLogix
over Data Highway Plus. Refer to page 17 for details.
You can use a DDE or OPC server such as RSLinx to access Data
Highway Plus using the AN-X-DHP. Refer to page 20 for details.
The AN-X-DHP module has a web interface for configuration of Data
Highway Plus station number and baud rate and for monitoring
diagnostic counters and the active station list. You can communicate
with the module using any standard web browser such as Internet
Explorer or Netscape.
AN-X-DHP Page 3
A watchdog timer is implemented in the module’s hardware. If the
firmware does not kick the watchdog within the timeout period the
watchdog times out and places the module into a safe fatal failure state.
A jabber inhibit timer is implemented in the module’s hardware. If the
network transmitter is on longer than 150% of the longest network frame
time, the transmitter is forced off and the module is placed into a safe
fatal failure state.
The module firmware can be updated over Ethernet using the Windows
utility supplied. Refer to page 41 for details.

Installation
Prevent Electrostatic Discharge
The module is sensitive to electrostatic discharge.
Electrostatic discharge can damage integrated circuits or
semiconductors. Follow these guidelines when you handle the module:
WARNING!
•
Touch a grounded object to discharge static potential
•
Do not touch the connector pins
Power
AN-X requires a DC power input of anywhere from 12 to 24 VDC
Left to right the pins on the power connector are chassis ground, negative
voltage and positive voltage.
The chassis ground should be connected.
Power consumption internally is 300 mA @ 12VDC or 150 mA @
24VDC.
The part number for the power connector is Phoenix MSTB
2.5/3-ST-5.08
Data Highway Plus Cabling and Termination
Follow Allen-Bradley cabling recommendations for Data Highway Plus.
Refer to Approved Vendor List for DH, DH+, DH-485, and Remote I/O
Cables, publication ICCG-2.2, February 1996.
The network cable must be terminated with terminating loads attached to
the physical ends of the network, usually 82 ohm, but refer to
Allen-Bradley documentation since some devices require 150 ohm
terminators. There should be two and only two terminators on the
network.
January 2008
Page 6 AN-X-DHP
From left to right on the AN-X module, the Data Highway Plus
connections should be line 1, shield, line 2.
The part number for the connector is Phoenix MSTB 2.5/3-ST-5.08
Ethernet Cabling
AN-X has a standard RJ-45 connector for connecting to Ethernet.
If you are connecting AN-X to an existing network through a router or
switch, use a standard Ethernet cable.
If you are connecting directly between a computer and AN-X, use a
crossover cable.
Software Installation
You must uninstall any previous version of the software before you can
install a new version. Use the Windows Control Panel Add and Remove
Programs to remove the old version.
Insert the CD supplied with the AN-X module and run the program
setup.exe on the CD.
January 2008
AN-X-DHP Page 7
Basic Configuration
The AN-X-DHP module connects a computer or other device on
Ethernet to a Data Highway Plus network.
Before you can use the AN-X-DHP, you must configure its network
properties, first on Ethernet and then on Data Highway Plus.
Ethernet Configuration
AN-X can be configured to use a static (unchanging) IP address or it can
be configured to obtain its IP address from a DHCP server.
Unless you have control of the DHCP server, in most applications you
will want to configure AN-X to use a static IP address. Otherwise the
DHCP server may assign a different IP address each time AN-X powers
up, and any software that accesses the AN-X module would have to be
reconfigured.
AN-X is shipped with DHCP enabled. If it finds a DHCP server on the
network, the DHCP server assigns it an IP address. You can use the
utility AnxInit to find the IP address that the DHCP server has assigned.
Select Utilities/Locate All AN-X Modules and AnxInit will locate the
AN-X and display its IP address.
If AN-X does not find a DHCP server within about three minutes of
starting up, it reverts to a temporary static IP address of 192.168.0.41 If
AN-X is using this temporary IP address, it repeatedly flashes the SYS
LED three times followed by a pause.
January 2008
Page 8 AN-X-DHP
IMPORTANT!
Use this temporary IP address only for initial setup of AN-X. AN-X will
not function for its intended purpose at the temporary IP address.
If you are using multiple AN-X modules, configure one at a time,
especially if there is no DHCP server on the network, since they will all
revert to the same temporary IP address when they fail to find a DHCP
server.
IMPORTANT!
If you are connecting AN-X to an existing Ethernet network, consult the
network administrator to obtain information about how you should
configure AN-X and to obtain a static IP address for AN-X.
IMPORTANT!
The AN-X must be on the local Ethernet (same subnet) when you set its
IP address.
You configure the Ethernet properties using the Windows utility AnxInit
supplied with AN-X.
Use the Configuration/AN-X IP Settings command to start the AN-X IP
configuration wizard, which takes you step by step through the IP
configuration process.
Step 1
In step 1, you identify the AN-X you are configuring.
1. Select the Ethernet adapter that’s connected to the AN-X. In most
cases there will be just one Ethernet adapter in the computer. The AN-X
must be on the same subnet as the computer.
January 2008
AN-X-DHP Page 9
2. Enter the MAC address of the AN-X you are configuring. This is
printed on the AN-X label. It consists of six pairs of hexadecimal digits,
separated by hyphens. In the example above, it’s 00-0c-1a-00-00-09.
If the AN-X is already online, you can obtain its MAC address using the
Utilities/Locate All AN-X Modules command.
3. Enter the IP address you intend the AN-X to use.
Step 2
In step 2, you choose a method of restarting AN-X to put it in boot mode.
The preferred method is to cycle power on the AN-X. Select the first
option on the screen and click the Next >> button.
The second method, useful if the AN-X in not easily accessible, is to
send it a command over Ethernet. The AN-X must be powered on and
completely running for this method to work. For example, if this is the
first time you are configuring a new AN-X, allow sufficient time for it to
acquire an IP address from a DHCP server or to time out and use its
default IP address (about 3 minutes). Select the second option on the
screen and click the Next >> button.
January 2008
Page 10 AN-X-DHP
Step 3:
Wait for AN-X to enter boot mode. While AnxInit is waiting, the
Next>> button will be disabled. When AN-X is in boot mode, the
Next>> button will be enabled.
If the AN-X does not enter boot mode within about 10 seconds, return to
the previous screens and check the entries.
The AN-X TCP/IP Configuration dialog appears.
January 2008
AN-X-DHP Page 11
Enter a Host Name for the AN-X. This name is used internally by AN-X
and may be used to identify the AN-X if you have a DNS server on your
network. The name can be from 1 to 31 characters long.
To configure the AN-X to obtain its IP address from a DHCP server on
the network, select Obtain an IP address automatically (DHCP)
To configure the AN-X to use a static IP address, select Use the
following Settings and enter:
•
the desired IP address for the AN-X.
•
the Subnet mask for the AN-X
•
the default gateway for your network.
You must enter a valid default gateway address even if there is no device
at the gateway address on the network.
Click OK to complete the configuration.
If you Cancel the Configuration/AN-X IP Settings command, AN-X is
left running the boot code. Use the Utilities/Restart AN-X command to
restart the AN-X.
Example: Standalone Computer
A typical example is a laptop computer running programming software
and connecting directly to an AN-X to program a PLC.
Since you are connecting directly from the computer to AN-X, use a
crossover Ethernet cable.
The following instructions assume Windows 2000. The procedure for
Windows NT and Windows XP is very similar. They also assume that
an Ethernet network card has been installed in the computer and that
AnxInit has been installed on the computer.
TIP
The parameters in this example will work when you set up any
standalone computer to work with AN-X.
First configure the computer to use a static IP address. From the Start
menu, select Start/Settings/Network and Dialup Connections. Double
click on Local Area Connection.
January 2008
Page 12 AN-X-DHP
Click the Properties button.
Double click on Internet Protocol (TCP/IP).
January 2008
AN-X-DHP Page 13
In this example, we will assign the computer an IP address of
192.168.0.10
Set the Subnet mask to 255.255.255.0 (standard mask for the Class C
network address of 192.168.0.x).
Set the Default gateway to 192.168.0.1 (this address does not exist on the
Ethernet network but AN-X requires a valid default gateway entry).
Click OK to accept the settings
Connect the computer to AN-X using the crossover cable.
If this is the first time you have used the AN-X module, it will look for a
DHCP server on the network. It waits about three minutes, then reverts
to a default IP address of 192.168.0.41
Power up the AN-X and wait for the search for a DHCP server to time
out. When the search for a DHCP server times out, AN-X will flash the
SYS LED red three times followed by a pause repeatedly.
Run AnxInit. Select Utilities/Locate All AN-X Modules and confirm that
the AN-X is found.
January 2008
Page 14 AN-X-DHP
Select Utilities/Select An AN-X and enter the MAC Address and IP
address.
Click OK to accept the setting.
Select Utilities/AN-X IP Configuration.
Enter an IP Address. In this case we chose 192.168.0.20
Enter the same Subnet mask and Default gateway that you entered for the
computer. The default gateway address does not exist on the network
but AN-X requires that the field have a valid entry.
Click Finish to accept the settings.
Select Utilities/Restart AN-X to restart AN-X with the new parameters.
When the AN-X has restarted (SYS LED is solid green), select
Utilities/Locate All AN-X Modules and confirm that the AN-X is found
with the new parameters.

Troubleshooting
LEDs
The AN-X-DHP has LEDs that indicate the state of the Ethernet
connection, the connection to Data Highway Plus, and the overall
module state.
Ethernet LEDs
There are two LEDs that indicate the state of the Ethernet connection.
The orange LED, labelled 100, is on if the link is running at 100
Mbits/second and is off otherwise.
The green Link/Act LED is off if the link is inactive and is on if the link
is active. If activity is detected, the link blinks at 30 ms intervals and
continues blinking as long as activity is present.
SYS LED
The SYS LED is used by the AN-X operating system and software to
indicate the state of operations and errors.
It should be used in conjunction with the logs to locate the cause of
problems.
In the following, red 3 means three red flashes followed by a pause, and
so on.
SYS LED State
Possible cause
Red 2
AN-X is in config mode
Red 3
DHCP configuration failed
Red 4
Fatal application error, check logs for cause
Red 5
Application memory access violation, check logs
Red 6
Application failed, illegal instruction, check logs
Red 7
Application crashed, unknown cause, check logs
Fast red flash
Reconfiguration (set station number and baud
rate) failed
Single red flash
Unscheduled messaging, addressing or
connection problem
Slow red flash
script or application problem during startup
January 2008
Page 38 AN-X-DHP
At startup, the SYS LED sequence is:
•
boot code starts – fast flashing red
•
boot code loads a kernel – solid red
•
if the configuration kernel is loaded, 2 red flashes followed by a
pause
•
if the production kernel loads with no errors, solid green
NET LED – Network Status
The NET LED indicates the status of the Data Highway Plus network
connection.
All stations operating correctly
Solid green
No other stations
Yellow
Network error
Flashes red
Data Highway Plus Diagnostic Counters
AN-X maintains Data Highway Plus diagnostic counters. Use
Automation Network/Monitor DH+ Network in the web interface to view
the diagnostic counters.
The counters are:
Counter
Description
Solicit ACK Bad
Solicit ACK bad (not to AN-X, bad ACK value, or source is
not the station AN-X solicited)
Transmit retries exhausted
AN-X retries messages up to 3 times (4 in total). If it still
hasn’t successfully sent the message, it discards the message
and returns an error.
Bad LSAP NAKs received
AN-X sent a message and got a bad LSAP NAK in response.
Usually caused by routing problems.
Received ACK/NAK too short
AN-X was waiting for an ACK and received a frame that was
less than 3 characters long instead.
Token pass timeout
AN-X passed the token but there was no response from the
destination in the timeout period. AN-X retries the token pass
up to 3 times.
Token claim sequence entered
AN-X increments this counter when there is no network
activity (no token passing, etc.). It then starts soliciting for
stations to pass the token to.
Bad CRC on received frame
AN-X received a frame with a bad CRC. Usually caused by

Counter
Bad LSAP NAKs sent
Description
cabling and termination.
AN-X uses this counter as a noise counter. If it detects a
carrier on the network and then the carrier disapperas before a
frame starts, it increments this counter.
Received frame too small
AN-X recievied a frame smaller that the minimum possible
size.
Retry of a frame received
AN-X received a frame with the same transaction number as a
previous frame. It discards the duplicate frame.
Messages successfully sent
AN-X increments this counter when it sends a message
(command or reply) successfully. It also increments the
commands successfully sent or replies successfully sent
counter.
Commands successfully sent
AN-X increments this counter when it successfully sends a
command to another station.
Commands successfully received
AN-X increments this counter when it receives a command
from another station.
Reply could not be sent
AN-X increments this counter when it receives a command but
could not deliver the reply.
ACK timeout
AN-X was expecting an ACK in response to a message but
nothing was received in the timeout period. Sometimes caused
by sending messages to stations that do not exist.
Illegal protocol NAKs received
No memory NAK received
AN-X sent a message and got an illegal protocol NAK in
response.
AN-X sent a message and got a no memory NAK in response.
Received ACK/NAK too long
AN-X was expecting an ACK and received a frame that was
longer than 3 characters instead.
Token pass retries exhausted
AN-X retries the token pass up to 3 times. If it still fails, it
increments this counter, removes the destination from its
active station list, and tries to pass the token to its successor.
Token claimed
Illegal protocol NAKs sent
No memory NAKs sent
Received frame too large
Receive frame aborted
Not used.
If AN-X receives a message that is shorter than the minimum
length (6 characters), it increments this counter and sends an
illegal protocol NAK to the sender.
IF AN-X receives a message and is out of buffer space, it
increments this counter and sends a no memory NAK to the
sender.
AN-X received a frame that was larger than the maximum
possible size (308 bytes, including the 2 CRC bytes).
AN-X increments this counter when it receives a message that

Counter
Description
doesn’t finish, either because the source aborted the message
or because the source went offline.
Messages successfully received
AN-X increments this cunter when it receives a message
(command or reply). It also increments the commands
successfully received or replies successfully received counter.
Replies successfully received
AN-X increments this counter when it receives a reply to a
command it sent to another station.
Replies successfully sent
AN-X increments this counter when it successfully sends a
reply to another station.
Counters roll over when they reach their maximum value.
The diagnostic counters are cleared when you reconfigure the Data
Highway Plus network parameters on AN-X.

Updating the Firmware
The AN-X operating software consists of several parts:
•
boot code, runs at startup
•
configuration kernel, runs when you update firmware
•
production kernel, runs in normal operation
•
application software, for Data Highway Plus communication and
unscheduled messaging
The boot code and kernels are supplied in file with extension qtf and are
updated using the AnxInit utility. Run the command Utilities/Update
AN-X Flash and select the file you wish to download. Refer to page 26
for details.
Firmware files contain the application programs for AN-X and have
extension bin. They are downloaded using the command
Configuration/Firmware Update or Utilities/Update Firmware in
AnxInit. Refer to page 27 for details.
Occasionally individual patch files are released. They have extension pch
and are downloaded using the Utilities/Patch Firmware command in
AnxInit. Refer to page 31 for details.
